bearkiller, in your sig you say you should install afuel pressure gauge as your first mod. why do you say that. my buddy has a 24v with the gauge but those where known to have fuel pressure probs. do the first gens?

 

fuel pressure gauge is a really good first mod, no there is no fuel probes

 

After you have been reading these threads a long time, you will see that there are numerous no-start/run-bad/no-power issues where the truck owner has no idea where to start looking for his problem.


The generic fix-all is "try a new fuel-filter"; whereas, a fuel-pressure reading will most likely save the expense of throwing away an otherwise good filter; two filters will pay for a gauge, one more will cover the various fittings necessary.


Also, the VE has a vane-pump that is capable of drawing fuel through a dead lift-pump, with the driver being none the wiser; many have found their lift-pump to have been completely dead for who knows how long; this lack of cooling/lubing fuel can be nothing but bad for the VE.


In a perfect situation, one should have a gauge on both sides of the filter.

These need not be in the cab; located somewhere in the engine compartment is fine, so long as the one on the down-stream side of the filter is in the cab (or readable from in the cab; it can be mounted on the cowl or the mirror, for that matter).

 

Once you start with the modifications it is not uncommon to pull down fuel pressure to nothing at WOT. VE's lubed with fuel, zero fuel pressure cannot be good as BearKiller has stated.
